Open Science Fair

Open Science Fair (OSFair) is organised as an emblematic initiative of OpenAIRE, a not-for-profit organisation to ensure a permanent open scholarly communication infrastructure to support European research. This year the event will be co-organised with and hosted by CERN Open Science Office. OSFair 2025 Theme “Fusing Forces – Accelerating Open Science through Collaboration” In an era where global challenges demand collective intelligence, OSFair 2025 will spotlight the power of global, international and cross-regional partnerships in shaping the future of Open Science. True progress requires collaboration that transcends borders, disciplines, and institutions—uniting diverse perspectives to drive meaningful change. This year’s OSFair will explore how diverse forms of collaboration can accelerate discovery, enhance knowledge accessibility, and create a more transparent and equitable research ecosystem. By fostering open and inclusive cooperation across continents, we can build a stronger, more connected scientific community. Join us from September 15th to 17th at CERN in Geneva as we come together to co-create the future of Open Science! Whether you're an advocate, practitioner, or newcomer, OSFair 2025 is your platform to connect and contribute.
